Aufgabe der Erfindung ist es ein Federungssystem für Kraftfahrzeuge, bei dem ein formveränderlicher geschlossener Hüllkörper vorgesehen ist, derart im Federungssystem zu fixieren, dass der Hüllkörper dicht und fest im Ausgleichsraum aufgenommen ist und gleichzeitig eine Strömungsverbindung vorsieht, die eine Befüllung mit Gas von außen ermöglicht.The object of the invention is Suspension system for Motor vehicles, in which a changeable closed envelope body is provided is to be fixed in the suspension system in such a way that the envelope body is tight and is firmly received in the compensation room and at the same time one Provides flow connection, the one filling with gas from the outside allows.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, dass das Anschlusselement in einer Bohrung der Kolbenstangenführung eingesteckt und unlösbar gehalten ist.To achieve this object, the invention provides that the connecting element is inserted into a bore in the piston rod guide and unsolvable is held.
Nach einem wesentlichen Ausführungsbeispiel ist des weiteren vorgesehen, dass in einer Nut der Bohrung ein Haltering angeordnet ist, der mit einer Abstützfläche des Anschlusselements zusammenwirkt. Vorteilhaft ist hierbei, dass der Hüllkörper mit einem Füllstutzen versehen wird, der vorzugsweise in die stirnseitige Verschweißung des Hüllkörpers eingebracht wird und dass der Füllstutzen als Schnappverbindung ausgebildet ist.According to an essential embodiment it is further provided that a retaining ring in a groove of the bore is arranged, which cooperates with a support surface of the connecting element. It is advantageous here that the envelope body with a filler neck is provided, which is preferably in the front weld of Envelope introduced will and that the filler neck is designed as a snap connection.
Eine weitere Ausgestaltung sieht vor, dass als Haltering ein federnder Ring vorgesehen ist.Another embodiment sees before that a resilient ring is provided as a retaining ring.
Nach einem weiteren wesentlichen Merkmal ist vorgesehen, dass die Nut einen Nutgrund aufweist, in den der Haltering eintauchen kann.After another essential A feature is provided that the groove has a groove base, in which the retaining ring can immerse.
Zum einwandfreien und leichten Fixieren des Hüllkörpers ist vorgesehen, dass der Haltering eine Einführschräge aufweist.For perfect and easy fixing of the enveloping body provided that the retaining ring has an insertion bevel.
Eine fertigungstechnisch einfache Ausführungsform sieht vor, dass zur Bildung der Nut die Bohrung eine Buchse aufweist.A technically simple embodiment provides that the bore has a bushing to form the groove.
Zur Erzielung einer einwandfreien Abdichtung des Ausgleichsraumes gegenüber dem Innenraum des Hüllkörpers ist vorgesehen, dass in der Bohrung eine Dichtung aufgenommen ist.To achieve a flawless Sealing of the compensation space against the interior of the envelope is provided that a seal is received in the bore.
Bevorzugte Ausführungsbeispiele sind in den Figuren schematisch dargestellt.Preferred embodiments are in the Figures shown schematically.
